Error compiling from source on fedora 37

Compiling rolling from source on Fedora I have the error for qt_gui_cpp:

--- stderr: qt_gui_cpp

both sip and python3-sip-devel are installed.

hi I've been trying to build qt_gui_cpp on Fedora 37 as well and faced the exact same error.

The error seems to originate from ld trying to call a file /builddir/build/BUILD/sip-4.19.25/.package_note-sip-4.19.25-5.fc37.x86_64.ld which I know definitely does not exist on our system, which motivated me to trace the origin of inclusion of this file in LFLAGS .

This led me to the file /usr/lib64/python3.11/site-packages/sipconfig.py,

_default_macros = {
    #...
    'LFLAGS': '-Wl,-z,relro -Wl,--as-needed  -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1  -Wl,--build-id=sha1 -Wl,-dT,/builddir/build/BUILD/sip-4.19.25/.package_note-sip-4.19.25-5.fc37.x86_64.ld',
    #...
}

Deleting the flag that leads to the inclusion of the .package_note file had allowed me to compile qt_gui_cpp successfully. I am unsure why is the flag there, but it seems to be a bug in either sip or package-notes-srpm-macros that causes this inclusion.

I have been trying to compile it using the version from pip in a venv but it doesn't work with:

CMake Warning at /home/malcolmmielle/rolling_ro2/install/python_qt_binding/share/python_qt_binding/cmake/sip_helper.cmake:25 (message):
  SIP binding generator NOT available.
Call Stack (most recent call first):
  src/qt_gui_cpp_sip/CMakeLists.txt:58 (include)


CMake Error at CMakeLists.txt:67 (message):
  No Python binding generator found.

Maybe because the sip version installed by pip is different? Just in case

@TK-Khaw solution didn't work for me and I hit other errors in the install. For now my solution is to ignore the package.
